To determine the characteristics of image formed we need to a draw ray diagram that uses

at least 2 rays that overlap each other

at least 3 rays out of 4 rays

plane mirror or lens

rays that passes through biconcave or biconvex mirror

The distance from center of mirror, C to the pole of mirror is given as

An image that is formed at the back of the mirror is said to be

real image

virtual image

inverted image

magnified image

An image is formed upside down in front of mirror and seems bigger by 2 times from the actual size. What might be the type of mirror uses?

concave mirror

convex mirror

plane mirror

concave lens

Which statement is true about convex mirror?

image formed is virtual and diminished

have a positive value of focal length

image formed is real and diminished

image formed is real and magnified

What is the formula for magnification?

-v / u

-h_i/ h_o

h_i/ h_o

v/u

State the characteristic of image foremd

real, inverted and diminished

virtual, upright and diminished

virtual, upright and magnified

real, upright and diminished

An image formed when the light rays pass through the image location, and could appear on paper or film placed at the that location is referred to as a

real image.

virtual image.

source image.

original image.

A spherical mirror on which reflection takes place on the inner surface of the sphere is referred to as a

convex mirror.

concave mirror.

convex lens.

concave lens.

10.

An object is positioned between a concave mirror's center of curvature and its focal point. The image produced by the mirror is located

out past the center of curvature.

at the center of curvature.

between the center of curvature and the focal point.

at the focal point.

11.

Concave spherical mirrors produce images which

are always smaller than the actual object.

are always larger than the actual object.

are always the same size as the actual object.

could be smaller than, larger than, or the same size as the actual object, depending on the placement of the object.

12.

A negative magnification for a mirror means

the image is inverted, and the mirror is concave.

the image is inverted, and the mirror is convex.

the image is inverted, and the mirror may be concave or convex.

the image is upright, and the mirror is convex.

13.

If R1 and R2 are the radii of curvature of a plano convex lens,

R1 is positive and R2 is negative.

Both R1 and R2 are negative.

R1 is positive and R2 is infinity.

R1 is negative and R2 is infinity.

14.

a convex lens does what to rays

diverges

converges

implodes

merges

15.

Concave lenses, like the ones found in the peepholes of a door, always produce images that are .....

Virtual, upright, smaller

Real, inverted, larger

Real, inverted, smaller

Virtual, upright, larger

16.

All rays that are parallel to the principle axis in a concave mirror reflects

Towards the focal point

Away from the focal point

Towards the center of curvature

Away from the center of curvature

17.

Which lens represents the path light takes through a diverging lens?

18.

If an object is place between F and 2F of a convex lens, the image will be
